When it is desired to form-recesses in the ends oftheblocks,` half cores 17L are secured Y Vto the slides ,19 as shown inA Fig. 6.

In .lieu of utilizing the slides 19 and part Vof the lower guides 21 tovform the ends oit the mold, such ends may beforined byplates 19e preferably formed integral with the forward ends of the guides 2Oa and 21a and securelybolted to the sides ofthe frame as j shown'in Figs. 16, 17, and 18.' When einploying such construction, the slides 19 areV extended only. a short distance kbeyond the cross, and to these extensions a. are securedY Vthe half cores 17a. In' lieu of forming the ond walls 'detachable from theV sidesv of the fraiiieof the machine, as shown in Figs. 1 17, and 18 and 19,V such sides may be fori with vportions 19b projecting 'inwardly and adaptedfto formI the end" wallsof the' mold as shown in Fig. 20. I f y bserved that the member 5 o 'It f will be .the cradle willreceive the transmitted inon pact of the' tampers and such stresses as Yarein part transmitted through the trunnion of the cradle to the cradle support 4. ln Yorderto r-elieve the YVsides of the machine of such transmittedstrains, the cradle supp-ort is in vturnY supported by the front spaier block 3.A When it isA desired to make a small block, e. g., an eight inch block, spacers 126 are interposed between the lower ends of thecradle support and the front spacer Vblock or -anvil When it is desired to malte a larger block, e. g., a twelve inch bloclgthev spacers 2G are removed and the cradle support'lowered onto the anvil block as shown innig. e.

the cradle'sup'port and a higher plate 16"L secured Vvon. the cradle support, the lower guide `moved down and correspondingly widerV 'slides 19a substituted for the sides 19. f Y

Each of the taniping-m-einbers consists of Va pair of rods 27 spaced a. suitable distance apart at their upper ends by a'sleeve surrounding the connecting bolt and at vtheir lower ends by a lug 29 on the tainping shoe 30, the shoe being detachably connected to the rods by a bolt. -The tainpers are guided in their movements by flat bars 31 passing between the rods of the several pairs and having their ends secured to the standards .32 which are secured'at their lower ends to the sides ofthe machine. The ltainpers are lifted Vto thel desired height by a cani 23 on a driven shaft 34 mounted Yin suitable bearings in the sides of the machine. As sli-ownin Fig. [1, this cam which operates on a roller 35 on the lever 36 looselyniounted on vthe shaft 24, is 'so constructedfthat' the initial upward movement of the lever will Another cradle .having thev mem- `ber 6 correspondingly higher is mounted in be sl-ow,and then gradually increaseto mid ,Y

position, then gradually decrease and will Vthen Vpermitl a free drop of the lever 'and the tainpers. The free ends of the levers connected by pitrnen 37 to the eiidsof a shaft -38Ywhiclji passes through slots39 in the that the latter will' 'pass between adjacent cores as shown in Fig. 9. As the series oftainping members extend the entire length of the inoldysomeof such members will; bev

in line lvertically with the cores, and hence provision ismade to hold the tainping menibers in line with theY cores in 'raised posi tion; the (otherk members are operated to tanip the `material' intermediate thecores.

Andv further, Aas the tainpers should notfoper-y ate while a completed block is beingrenioved andl the cradle returned to operative posi# tion, provision is made for holding all the ine pans oi cars carrying tiie "so by means of blocks/41, carried by rods se' l'ilh'en' shaping tampers andl also ap'ortion ofthe tampers in Yraised position. ln the construction shown in Figs. 1't0 2C, studs 42 are secured to the standards 32 and on these studsv are mounted lingers adapted Yto be shifted under the shaft 38,7when in raised position, as shownin Fig. 2. The fingers 43 are con'- nected byv bar 44 adapted to be shifted to position to engageV lugs 45 on such of `the' tainping members as arein line vertically with .the cores. rlhese lugs project such' a distance from the tainpers that the lingers can be moved out of alineinent with the shaft 38 while bar 44 is in yengagenient with the lugs '45 as shown in F ig. Y2C. A desirable means for operating these devices consists in connecting an arm 46 on one of the iingers 43 to a lever 47`by a rod 48. This lever passes along a segment 49 and is provided with means as a pin 50 for engaging holes in the segment. These holes in thesegment are so located that the fingers 43 may be held in engage-ment with the shaft 38, or by nioving'the lever 47 down' to the next hole the lingers willv be moved out of engagemeifitY with the shaft, but the bar 44 will remain in with the lugs 45. a'fnrther movement of the lever 47V the bar 44 willfbe moved out of enga-genient'with the lugs 45; ltV is pieferred that the rod 48 should pass freely through the arin 46 and to arrange springs 51 *andV 52 above and below' said arm, said springs bearing on opposite sides of thear'ni im) Y g Y and collars 531` onk 'the rod.' `11n practice', 'they sliaftSS will'be raiseda shortfdist'anfe above' f Ithe fingers -andbar,` and when the shaft .drops down. onto'- the Vfingers or ,b ar', the upper spring-51 'will serve asaa cushion.` In case Athe operating, lever 47 4isfshifted while the' Ashaft 3,8V orI lugs'4'5 aiebelow theilingers 'and bar', 'the flower f spring will allowy the fingers and barto move-outwardly.

A hopper 5 4 for concrete orother is arranged in'suchifelationv tothe op'en'side ofthe 1.mold when inoperative position, that 'the material can-'be forced lthrough an operiing' at the lower end of theV hopper into 'the mold. The material is forced vthrougigh this VopeningV by a plunger 56. This plunger Y is connected by a link 57 to an arm 5801i the Y shaft 59, which canA be rotated to recipro- After a new pallet has beenipla'ced in posi` catel the plungerfby alever 6'0 eitendi'ng toward thefront of the machine, las shown inl Fig. 11`, or-any'other. suitable means?
